## 1. Role

### JKKNsidPwdChgOrsjgsCC.chgNsidPwd()

The `chgNsidPwd` method is the central entry point for **Authentication ID Password Change for Downstream Business Partners** (`認証IDパスワード変更(卸先事業者)`) in the K-Opticom e-Customer Core System. It handles the end-to-end business process of changing or initializing an ISP authentication ID password for customers associated with downstream business partners (sub-dealers/resellers).

The method implements a **conditional dispatch/routing pattern** based on the `categoryOfChange` field extracted from incoming request parameters, branching into two distinct business flows: (1) **Change (`変更`)** — modifies the existing ISP authentication ID password, registering the request as a service order and triggering SOD (Service Order Data) issuance; and (2) **Initialization (`初期化`)** — resets the authentication credentials to their original state via the ID/PW initialization/reissue CBS.

Before dispatching, the method performs comprehensive **precondition validation** through `chkKnrn`, verifying contract existence, downstream business partner eligibility and validity period, and authentication ID existence — ensuring the customer's service contract is in an acceptable state for modification.

The method serves as a **shared utility component** called by screen operation handlers (specifically KKSV0901), making it a critical cross-cutting service for password management across the e-Customer portal. It orchestrates interactions with multiple Service Components (SCs) and CBSs, managing a full lifecycle from validation through submission, SOD issuance, and response assembly.

**Processing Flow Summary:**

1. **Parameter Extraction**: Retrieves the `ccMsg` map from `param.getData(fixedText)` — this contains authentication ID password change parameters including `channel`, `commonKey`, `authenticationId`, `authenticationIdPassword`, `categoryOfChange`, etc.

2. **Service Component Request Invoker Creation**: Instantiates `ServiceComponentRequestInvoker scCall` for SC invocation routing.

3. **Validation (`chkKnrn`)**: Performs multi-layered precondition checks (see Block 1 detailed analysis below).

4. **Branch Routing by `categoryOfChange`**:
   - **Branch 1 (`"1"` — Change)**: Registers acceptance content, changes ISP authentication ID password, registers progress, and issues a Service Order.
   - **Branch 2 (`"2"` — Initialization)**: Prepares and executes ID/PW initialization/reissue via `JKKIdPwdShkkaSaifurHakkoCC.executeShkkaHakko`.

5. **Response Assembly**: Sets normal response code and returns `param`.

6. **Error Handling**: Catch block catches any `Throwable`, sets system error response, and re-throws.

## 5. Dependency Trace

| # | Caller (Screen/Batch) | Call Chain (Full Path to this Method) | Terminal (SC / CRUD / Entity) |
|---|----------------------|--------------------------------------|-------------------------------|
| 1 | Screen:KKSV0901 | `KKSV0901OPOperation.target1` (CCRequestBroker) -> `JKKNsidPwdChgOrsjgsCC.chgNsidPwd` | EKK0081A010 [R] KK_T_SVC_KEI; ECK0011A010 [R] KK_T_CUST_KEI; ECH0911A010 [R] KK_T_ORSJGS; EKK0171B001 [R] KK_T_AUTH_ID_NINSHO; EKK0011D020 [C] KK_T_MSKM; EKK0021C060 [R] KK_T_MSKM_DTL; EKK0171B002 [R] KK_T_AUTH_ID_PWD; EKK0171C012 [U] KK_T_SVC_KEI_UCWK; EKK1091D010 [C] KK_T_PRG; JKKHakkoSODCC [C] SOD; JKKIdPwdShkkaSaifurHakkoCC [C] ID/PW Init |

**Note:** The primary entry point is the KKSV0901 screen operation. The `KKSV0901OPOperation` class uses a `CCRequestBroker` to invoke `chgNsidPwd` with the following parameters:
- CC Target: `com.fujitsu.futurity.bp.custom.common.JKKNsidPwdChgOrsjgsCC`
- CC Method: `chgNsidPwd`
- CC Target Class Name: `KKSV090101CC`
- Exception Judge: `DefaultCCExceptionJudge`

This is the only caller found in the codebase. The KKSV0901 screen serves as the user interface for authentication ID password changes for downstream business partners.
